| Leftovers: IBM, Mozilla and SUSE
-
The continuous delivery software that's been doing the heavy lifting on IBM's global Kubernetes platform is now open source.
-
Mozilla’s View Source Conference is back for a fifth year, this time in Amsterdam, September 30 – October 1, 2019. Tickets are available now.

If you haven’t been hanging around the Ceph world for a bit, you may not realize that Ceph was originally intended to provide a distributed file-system to service HPC clusters. While this was the original intent, Ceph has taken a round-a-bout path to relevance in this space, especially given that we are only supporting multiple active MDS servers since the Luminous release. The result is that we are, only now, really starting to see adoption in the HPC space, and mostly for the second tier storage needs.
Enter, the science project. Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?

By throwing a lot of man power on it. As the primary author and developer of the libcurl API and the libcurl code, I assume that Cronet works quite differently than libcurl so there’s going to be quite a lot of wrestling of data and code flow to make this API work on that code.
The libcurl API is also very versatile and is an API that has developed over a period of almost 20 years so there’s a lot of functionality, a lot of options and a lot of subtle behavior that may or may not be easy or straight forward to mimic.
The initial commit imported the headers and examples from the curl 7.65.1 release.

Coders use Google Cloud Platform (GCP) more than Microsoft Azure, though Amazon Web Services (AWS) has a comfortable lead, according to a Developer Ecosystem survey conducted by tools vendor JetBrains.
Developer usage is 67 per cent AWS versus 28 per cent GCP and 21 per cent Azure, according to the new survey. Unfortunately, the question was posed in a different way in the 2018 survey, adding on-premises into the mix, but last year Azure and GCP had equal share after AWS.
The survey had 19,000 participants invited via "Twitter ads, Facebook ads, Google Adwords and JetBrains' own communication channels," the tools vendor said, though "only the responses of 6,993 respondents were included in the report." Responses were removed to reduce bias, yet it warned "some bias may be present as JetBrains users may have been more willing on average to compete the survey".

While as of Linux 5.2 the support for Intel's Icelake CPUs appear production ready with all of the bits in place from new IDs to the much enhanced "Gen 11" graphics, there are a few stragglers of items to land with the upcoming Linux 5.3 merge window though could be back-ported to current series. Fortunately, we haven't found anything major to be missing.
One of the latest bits of Icelake Linux support is handling of these next-generation processors within the PowerCap / RAPL (Running Average Power Limit) driver code. In particular, the desktop/workstation Icelake parts. This is the code for reading the estimated CPU package power consumption based on hardware performance counters and the ability to artificially limit the power draw of the processor via software.

Eight Navi GPU variants have been spotted in Linux driver code. AMD’s next-gen RDNA graphics chips are set for launch on July 7, 2019 within the RX 5700 XT and RX 5700, but the red team has plenty of silicon in store for a range of applications. Including console, laptops, desktop, and mobile phones.
The GPU codenames were spotted within Linux display drivers after the additional code was submitted and signed off by two AMD employees. The code adds support for Display Core Next, or DCN2, which “is the display block for Navi10.” Each entry following adds the necessary ASIC IDs for each Navi chip in the stack, starting with Navi 10 and down to Navi 21 LITE.

Building off the initial Turing mode-setting bits that were in place since Linux 5.0 and have continued stepping along to support newer variants on successive kernel releases, the Linux 5.3 kernel is slated to add support for the TU116 graphics processor.

With the increasing demand for bandwidth across a wide range of devices used in consumer and enterprise domains, PCI Express, the high-speed serial computer expansion bus standard has also evolved over the years.
PCI Special Interest Group, a body that sets standards for PCIe, has announced PCI Express 6 that promises four times the bandwidth offered by PCIe 4.0 and twice of PCIe 5.0.
-
While PCI Express 4.0 up to this point has only been found in a few systems like Talos' POWER9 platforms and coming soon with the new AMD graphics cards and chipsets, the PCI SIG today announced PCI Express 6.0.
PCI Express 5.0 was only announced last month with 32GT/s transfer rates while already the PCI SIG announced PCI Express 6.0.
